JOHN O. MCKEAN, 0F VIESTFIELD, MASSACHUSETTS, ASSIGIJGR TO FOSTER MACHINE COMPANY, OF WESTFIELD, MASSACHUSETTS, A CORPORATION OF MASSACHUSETTS YARN-COMPENSATING DEVICE FOR OREELS.

Application filed November It has been practically impossible to keep yarn from kinking as it passes from the yarn supply to the Warping machine. This is especially true when the warping machine stops and the yarn is at rest.

tical rods around each or which rods the yarns from one or more rows of cops are wound as they pass from their cops, said vertical rods allowing the yarns to drop by gravity on said rods to automatically take up slack in the yarns when their travel is stopped.

Fig. 8, looking in the direction of the arrows.

T he creel frame is denotedbv 1. ThecopsQ are arranged in a plurality of vertical rows, the holders 8 for the cops of each vertical row being carried by a' vertically disposed supporting bar 4 pivoted in the creel frame 1,

to rock on a vertical axis to s "ing the cops to and fromtheir doiling position.

In proximity to each vertical supporting bar 4 I mount a vertically disposed rod 5 in the creel frame 1, around which rod the yarns A practical embodiment of my invention. is represented in the accompanying draw- 11, 1925. Serial No. 68,367.

are wound as they pass from their cops to the warping machine (not shown herein).

Therod 5 which acts as the yarn compensating device is provided with a vertical row of brackets 6, each of which carries a tension device 7 of any well known or approved construction, through which tension device the yarn passes after it leaves the bar 5. I have found that by winding the yarn around the P bar 5 on its way from the cop to the tension device, the bar operates to keep the yarn coinparatively taut Whether the yarn is or is not running, thereby tending to take the kinks out of the yarn when the yarn is running-and also to keep the yarn from kinking when it is at Furthermore, the tension device through which the'yarn passes also-tends to take those kinks out of the yarn which have not already been taken out by the compensating device.

that I claim is:

l. A yarn supply, a yarn tension device lo cated below the yarn supply and a vertically disposed rod around which the yarn is wrapped at least once as it passes from the yarn supply to the tension device, said rod operating to keep the yarn comparatively taut when the yarn is running and at rest, thereby tending totake out the kinks when running and to keep the yarn fr-07in kinking when at rest.

. 2. A plurality of yarn supplies, a plurality of yarn tension devices located below their respective yarn supplies and a vertically disposed rod around whichthe yarns are wrapped at least once as they pass from the yarn supplies to their respective tension devices, said rod operating tokeep the yarns comparatively taut when the yarns are running and at rest, thereby tendingto' takeout the kinks when running andto keep the yarns from kinking when at rest.

In testimony, that I claim the foregoing as my invention, I have signed my name this 9th day of NOV. 1925.
